Unfortunately if you don't have access to the computer then no we cannot retrieve those files, but if you put the files on a CD rom disk or USB you can simply load them on to another computer. I'm sorry, but the only place your 2015 return is saved/stored is on the computer that you used to prepare and file that return. Unless you saved a digital copy of your 2015 tax data file and/or a PDF file, you'll have to begin again from scratch.
